Summary: | 碩士 === 國立臺灣大學 === 電信工程學研究所 === 89 === Dual-band printed antennas for vehicle applications are analyzed and both theoretically and experimentally in this dissertation. The analysis is based on the method of moments solved in the spectral domain. Parameter studies are also realized with the aid of IE3D software. Computed results for the input impedances are given and compared with measured data. Good agreements between theory and experiments are obtained.
Investigation begins with the verifications of numerical method. Two kinds of numerical examples are presented to demonstrate the validity of this program. A dual-band printed inverted-F antenna that the ground and the radiator are coplanar is proposed. Impedance matching can be easily achieved by the extending arm and resonant frequency is determined by the arm length of this antenna. The printed inverted-F antenna has a low profile and can be printed on glass in the form of heat-reduction grids. This proposed antenna is low-cost, easy to fabricate, and has a dipole-like radiation pattern. Another kind of dual-band antenna proposed in this dissertation is printed dipole antenna. The resonant mechanism of dual frequency for printed dipole antenna is introduced in this dissertation. Parameter studies are presented in the following sections.
